Anthocyanidins are a group of active ingredients found in brightly colored fruits, and the scientific communitys interest in anthocyanidins has focused on their role in strengthening collagen. Collagen is the most abundant protein in the body, being the main structural protein of the connective tissue of the skin, muscles, ligaments, cartilage and capillaries, and numerous publications report the beneficial effect of anthocyanidins on strengthening, rebuilding and maintaining collagen. Many pathological conditions are caused by the disruption of the structure and functionality of collagen, such as degenerative osteoarthritis, the tendency to bruise due to disruption of the structure of the capillary wall, and the appearance of edema of the lower extremities (venous insufficiency). The fact that the active ingredients of Colladeen Maximum Strength contribute to the restoration of collagen structure makes it an invaluable dietary supplement in situations where collagen reinforcement is required.
